Graphical user interface for querying relational data models

ABSTRACT

Some embodiments provide a non-transitory machine-readable medium that stores a program executable by at least one processing unit of a device. The program receives a selection of a first entity and a second entity in a relational data model. The relational data model includes several entities and a set of relationships among the several entities. The program also determines a set of navigation routes through the relational data model based on the first and second entities. The program further provides the determined navigation routes through a graphical user interface (GUI) in order to provide a visual context of data in the relational data model.

BACKGROUND

Computing systems (e.g., enterprise systems) may be used for managing large amounts of data. Different computing systems may manage data using different techniques. For instance, some computing systems store data based on to a relational data model. In such a model, data is organized and/or stored according to defined entities and relationships among the entities.

In some instances, a computing system may export data to another computing system (e.g., a third-party system). For complex relational data models that have a large number of entities and/or relationships, identifying the desired data to export to another computing system may be difficult and/or time consuming. For example, a user of the computing system may need to manually traverse through the relational data model in order to identify the desired data.

When a computing system exports data to another computing system, the other computing system may expect data that is not directly available from the attributes of an entity. For example, the other computing system may require data that includes street, city, state, and zip code in a single string while the computing system may store the street, city, state, and zip code as separate attributes of an entity. In such an example, the computing system may aggregate the attributes into a single string before exporting the data to the other computing system.

SUMMARY

In some embodiments, a non-transitory machine-readable medium stores a program executable by at least one processing unit of a device. The program receives a selection of a first entity and a second entity in a relational data model. The relational data model includes several entities and a set of relationships among the several entities.

DETAILED DESCRIPTION

In the following description, for purposes of explanation, numerous examples and specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one skilled in the art that the present invention as defined by the claims may include some or all of the features in these examples alone or in combination with other features described below, and may further include modifications and equivalents of the features and concepts described herein.

Described herein are techniques for providing routes through a relational data model. In some embodiments, a relational data model defines entities and relationships among the entities. Each entity may include one or more attributes and one or more relationships. A relationship between two entities may specify a type of relationship (e.g., a one-to-one relationship, a one-to-many relationship, a many-to-one relationship, a many-to-many relationship, etc.). In some embodiments, a user specifies an entity in the relational data model as a starting entity and an attribute of another entity in the relational data model as a target entity. Based on the starting entity, target entity, and relational data model, several routes through the relational data model are presented to the user for selection. In some embodiments, the routes are presented to the user through a graphical user interface (GUI) in order to provide a visual presentation of the context of data.

FIG. 1 illustrates a data flow of a system 100 for integrating data according to some embodiments. As shown, system 100 includes data source 105, data integration manager 110, and systems 115 a-n. In some embodiments, data source 105 and data integration manager 110 are part of the same system while, in other embodiments, data source 105 and data integration manager 110 operate on separate systems.

Data source 105 is configured to provide data to data integration manager 110. In some embodiments, data source 105 stores and manages data based on a relational data model. For example, data source 105 stores data that describes entities defined by the relational data model and data that describes relationships among the entities defined by the relational data model. In some embodiments, data source 105 is implemented by several storages (e.g., hard disk storages, flash memory storages, optical disc storages, etc.) while, in other embodiments, data source 105 is implemented by a single storage. In some embodiments, data source 105 is a database, a file, a data as a service (DaaS), a web service, etc.

Data integration manager 110 may be configured to provide data from data source 105 to systems 115 a-n for integration into systems 115 a-n. As shown in FIG. 1, data integration manager 110 is receiving exported data from data source 105. In some embodiments, data integration manager 110 retrieves the exported data from data source 105 while, in other embodiments, data source 105 sends the exported data to data integration manager 100 in response to data integration manager 110 sending data source 105 a request for the exported data. Upon receiving the exported data, data integration manager 110 sends the exported data to a system 115 as data for integration into the system 115. In some embodiments, the exported data is sent to a system 115 as a file according to a file format (e.g., a comma-separated values (CSV) file).

In some embodiments, before sending the exported data to a system 115, data integration manager 110 may format the exported data according to a certain format in which the system 115 expects the data. For example, a system 115 may expect to receive address data (e.g., street, city, state, zip code, etc.) as a single string, as a collection of strings and/or numbers, etc. As another example, a system 115 may expect to receive name data (e.g., first name, middle name, last name, etc.) as a single string, as a collection of strings and/or numbers, etc. One of ordinary skill in the art will appreciate that any number of different types of data may be formatted any number of different ways.

Data integration manager 110 may perform data integration operations at different times. For example, data integration manager 110 may perform a data integration operation at a specified time (e.g., a scheduled time), at defined intervals (e.g., once a day, once every five days, once a week, once a month, etc.), in response to a request from a system 115, etc.

In some embodiments, data integration manager 110 is a data integration service or tool that is part of a multi-tenant, cloud-based system implemented using a software as a service (SaaS) methodology. One of ordinary skill in the art will understand that data integration manager 110 may be part of any number of different systems (e.g., a human capital management (HCM) system, an enterprise resource planning (ERP) system, a customer relationship management (CRM) system, a supply chain management (SCM) system, a product lifecycle management (PLM) system, etc.).

Systems 115 a-n are configured for receiving data stored in data source 105 via data integration manager 110. In some embodiments, a system 115 may expect data that system 115 receives from data integration manager 110 to be in a certain format (e.g., by sending to data integration manager 110 a request to send data to the system 115 according to the certain format). For example, a system 115 may expect to receive address data (e.g., street, city, state, zip code, etc.) as a single string, as a collection of strings and/or numbers, etc.

Systems 115 a-n may be third-party systems that operate on computing systems separate from data source 105 and data integration manager 110. Examples of third-party systems include a payroll system, a background screening system, a finance system, a learning management system (LMS), a human resource management system (HRMS), a human resources information system (HRIS), a time management system, an employee benefits system, etc.

As illustrated in FIG. 1, system 100 includes one data source. One of ordinary skill in the art will realize that system 100 may include any number of additional and/or different data sources from which data integration manager 110 may integrate data into systems 115 a-n.

As mentioned above, data source 105 may store and manage data based on a relational data model. FIG. 2 illustrates an example relational data model 200 according to some embodiments. In this example, relational data model 200 defines entities and relationships among the entities for describing personal information and employment information associated with people. As described above, a relational data model defines entities and relationships among the entities in some embodiments. Each entity may include one or more attributes and one or more relationships.

As illustrated in FIG. 2, relational data model 200 includes email info entity 205, email type entity 210, personal info entity 215, person entity 220, employment info entity 225, dependents entity 230, and job info entity 235. For this example, email info entity 205 represents information associated with an email, email type entity 210 represents a type of email, personal info entity 215 represents personal information associated with a person, person entity 220 represents a person, employment info entity 225 represents information associated with a place of employment, dependents entity 230 represents a dependent of a person, and job info entity 235 represents information associated with a job. As shown in FIG. 2, personal info entity 215 includes a first name attribute and a last name attribute. One of ordinary skill in the art will understand that entities 205, 210, 215, 220, 225, 230, and 235 may include any number of additional and/or different attributes. However, for the purposes of simplicity and explanation, attributes of entities 205, 210, 215, 220, 225, 230, and 235 are not shown except for the first name and last name attributes of personal info entity 215.

As explained above, a relationship between two entities may specify a type of relationship (e.g., a one-to-one relationship, a one-to-many relationship, a many-to-one relationship, a many-to-many relationship, etc.). FIG. 2 illustrates relationships 250, 255, 260, 265, 270, 275, 280, and 285 among entities 205, 210, 215, 220, 225, 230, and 235. In this example, a person has one or more places of employment, one set of personal information about the person, and one or more dependents. As such, relationship 265 between person entity 220 and employment info entity 225 is a one-to-many relationship with, relationship 260 between person entity 220 and personal info entity 215 is a one-to-one relationship, and relationship 275 between person entity 220 and dependents entity 230 is a one-to-many relationship, respectively.

For a place of employment in this example, a person has one or more jobs at the place of employment. Thus, relationship 280 between employment info entity 225 and job info entity 235 is a one-to-many relationship. In this example, a person has one manager for each job. This relationship is defined in relational data model 200 through relationship 285 between job info entity 235 and employment info entity 225, which is a one-to-one relationship. Specifically, a relationship 285 represents a relationship between the job information of a person and the employment information of the person's manager. In this example, employment information of a manager of a person may be accessed by navigating from job info entity 235 to employment info entity 225 via relationship 285. The personal information of the manager of the person may be accessed by continuing to navigate from employment info entity 225 to personal info entity 215 via relationships 265 and 260.

A dependent in this example has one set of personal information about the dependent. Accordingly, dependent entity 230 has a one-to-one relationship with personal info entity 215. In this example, the personal information for a person has one or more emails. As such, personal info entity 215 has a one-to-many relationship with email info entity 205. Each email in this example may be of a certain type (e.g., personal email, business email, secondary email, etc.) and many emails may be of the same type. Thus, email info entity 205 has a many-to-one relationship with email type entity 210.

As described above, FIG. 2 illustrates an example relational data model. One of ordinary skill in the art will appreciate that the entities, relationships, and types of relationships depicted in FIG. 2 are used for the purposes of simplicity and explanation and that relational data model 200 may include any number of additional and/or different entities, relationships, and/or types of relationships.

FIG. 3 illustrates an architecture of data integration manager 110 according to some embodiments. As shown, data integration manager 110 includes a user interface (UI) manager 310, a navigation manager 315, and a data manager 320. UI manager 310 is configured to provide UIs (e.g., GUIs, command line interfaces (CLI), etc.) to client 305 for interacting with the data integration manager 110. Client 305 may be any type of computing device (e.g., a mobile device, a smartphone, a laptop, a desktop computer, a tablet, etc.). Client 305 may include a thin client (e.g., a web browser) configured to interact with the UIs provided by UI manager 310. In some embodiments, client 305 and data integration manager 110 operate on the same computing device while, in other embodiments, client 305 and data integration manager 110 operate on separate computing devices.

Navigation manager 315 is responsible for navigating through a relational data model (e.g., relational data model 200) to identify routes through the relational data model. Navigation manager 315 may receive a request from UI manager 310 to determine routes through a relational data model. In response to such a request, navigation manager 315 may access the relational data model in data models 325, which is configured to store relational data models, in order to determine routes through the relational data model. Upon determining routes through the relation data model, navigation manager 315 sends the determined routes to UI manager 310.

Data manager 320 may handle retrieving data from data source 105 and sending the retrieved data to one or more systems 115 for integration into the one or more systems 115. In some embodiments, before sending the retrieved data to a system 115, data manager 320 may format retrieved data according to a certain format in which the system 115 expects the data. Data manager 320 may receive a request from UI manager 310 to integrate data from data source 105 to one or more systems 115. The request may specify the data for integration, a relational data model, a route through the relational data model to access the data for integration, and one or more systems 115. In response to the request, data manager 320 retrieves the requested data from data source 105 based on the relational data model and the route through the relational data model. Upon retrieving the requested data from data source 105, data manager 320 sends the retrieved data to the specified one or more systems 115.

In some instances, a user of client 305 may want certain data in data source 105 for integration into a system 115. For example, the user may want to integrate the last name of a manager of each person in data source 105 into a system 115. However, different routes through relational data model 200 may yield different last names. For instance, a route may yield the last name of a person, another route may yield the last name of a dependent, another route may yield the last name of a manager, etc. An example data integration operation for integrating the last names of managers will now be described by reference to FIGS. 2-5.

FIG. 4 illustrates a process 400 for providing routes through a relational data model according to some embodiments. In some embodiments, data integration manager 110 performs process 400. Process 400 starts by receiving, at 410, a selection of a starting entity in a relational data model. Referring to FIG. 3 as an example, UI manager 310 may perform operation 410 by receiving a selection of a starting entity in a relational data model from client 305 through a GUI that UI manager 310 provides to client 305. In this example data integration operation, a user of client 305 selects through the GUI (e.g., via a dropdown menu, a text box control, a selectable UI item, etc.) person entity 220 in relational data model 200 as a starting entity.

Next, process 400 receives, at 420, a selection of a target entity in the relational data model. Referring to FIG. 3 as an example, UI manager 310 may perform operation 420 by receiving a selection of a target entity in the relational data model from client 305 through a GUI that UI manager 310 provides to client 305. In some embodiments, the selection of a target entity includes a selection of one or more attributes of the target entity. For this example data integration operation, a user of client 305 selects through the GUI (e.g., via a dropdown menu, a text box control, a selectable UI item, etc.) the last name attribute of personal info entity 215 in relational data model 200 in order to select personal info entity 215 as a target entity.

Process 400 then determines, at 430, navigation routes through the relational data model based on the starting entity and the target entity. Referring to FIG. 3 as an example, UI manager 310 may send the selected starting entity and target entity to navigation manager 315 and instruct navigation manager 315 to perform operation 430. After navigation manager 315 determines navigation routes through the relational data model, navigation manager 315 sends the determined navigation routes to UI manage 310.

In some embodiments, process 400 determines a navigation route through the relational data model by beginning at the starting entity in the relational data model, traversing through the relational data model based on the relationships between the entities in the relational data model until arriving at the target entity. The starting entity, the entities through which the relational model is traversed, and the target entity collectively form the navigation route. In some embodiments, process 400 limits the navigation route to a defined number of entities (e.g., five entities, seven entities, ten entities, etc.). Thus, in some such embodiments, process 400 starts determining a new navigation route through the relational data model when process 400 has traversed the defined number of entities in the relational data model and has not arrived at the target entity.

In some embodiments, when process 400 determines a next entity to traverse to when determining a navigation route, process 400 considers an entity in the relational data model other than the previous entity in the navigation route. Referring to FIG. 2 as an example, if process 400 traverses from personal info entity 215 to person entity 220 via relationship 260 for a navigation route, process 400 may consider, as a next entity to traverse to for the navigation route, traversing from person entity 220 to dependents entity 230 via relationship 275 or from person entity 220 to employment info entity 225 via relationship 265. Process 400 does not consider traversing from person entity 220 to personal info entity 215 because process 400 traversed to person entity 220 from personal info entity 215.

After determining navigation routes through the relational data model, process 400 provides, at 440, the determined navigation routes. Referring to FIG. 3 as an example, UI manager 310 may perform operation 440 by providing the determined navigation routes to client 305 through a GUI that UI manager 310 provides to client 305. Continuing with the example data integration operation, UI manager 310 provides navigation routes that include person entity 220 as the starting entity and personal info entity 215 as the target entity. FIG. 5 illustrates a GUI 500 for providing navigation routes through a relational data model according to some embodiments. For this example data integration operation, UI manager 310 provides determined navigation routes to client 305 via GUI 500. As shown, GUI 500 includes text box control 505, navigation route panel 510, relationship path panel 550, and selectable UI items 555 and 560.

Text box control 505 receives input for selecting attributes of a target entity in a relational data model. In this example, a user of client 305 specified the last name attribute of personal info entity 215 in text box control 505 in order to select the last name as the requested data and personal info entity 215 as the target entity. Selectable UI item 555 is configured to terminate the navigation route selection operation and selectable UI item 560 is configured to select a navigation route for a data integration operation.

Navigation route panel 510 is configured to display determined navigation routes through a relational data model. As shown, navigation route panel 510 includes navigation routes 515, 520, and 525. In this example, addition navigation routes are included in navigation route panel 510. The additional navigation routes are not displayed but viewable via scroll bar control 530. Navigation route 515 starts at person entity 220 and ends at personal info entity 215 via relationship 260. As such, traversing through relational data model 200 via navigation route 515 accesses the last name of a person. Navigation route 520 starts at person entity 220, traverses through dependents entity 230 via relationship 275, and ends at personal info entity 215 via relationship 270. Thus, traversing through relational data model 200 via navigation route 520 accesses the last name of a dependent of a person. Navigation route 525 starts at person entity 220; traverses through employment info entity 225, job info entity 235, and employment info entity 225 via relationships 265, 280, and 285, respectively; and ends at personal info entity 215 via relationship 260. Therefore, traversing through relational data model 200 via navigation route 525 accesses the last name of a manager of a person. As illustrated, the navigation routes displayed in navigation route panel 510 provide a visual representation of the context of the requested data (the last name of personal info entity 215 in this example).

Relationship path panel 550 is configured to display a relationship path of a navigation route selected in navigation route panel 510. Referring to FIG. 3 as an example, UI manager 310 may receive a selection of a determined navigation route from client 305 through GUI 500. In some embodiments, UI manager 310 provides a relationship path of the selected navigation route in relationship path panel 550 in response to the selection. In other embodiments, client 305 processes the selection and provides a relationship path of the selected navigation route in relationship path panel 550 in response to the selection.

In this example, navigation route 525 is selected in navigation route panel 510 as indicated by a highlighting of navigation route 525 in navigation route panel 510. Relationship path panel 550 is displaying a relationship path associated with navigation route 525 as indicated by a highlighting of relationships traversed along navigation route 525. As shown, the relationships traversed along navigation route 525 include relationship 265 (from person entity 220 to employment info entity 225), relationship 280 (from employment info entity 225 to job info entity 235), relationship 285 (from job info entity 235 to employment info entity 225), relationship 265 (from employment info entity 225 to person entity 220), and relationship 260 (from person entity 220 to personal info entity 215).

As illustrated in FIG. 5, the relationships displayed under an entity in relationship path panel 550 show the possible relationships that may be traversed from the entity. For instance, relationships 265, 260, and 275 are displayed under the starting entity of navigation route 525 in the first column since relationships 265, 260, and 275 are the possible relationships that may be traversed along from person entity 215. As another example, relationships 280 and 265 are displayed under the second entity of navigation route 525 in the second column since relationships 280 and 265 are the possible relationships that may be traversed along from employment info entity 220. As such, relationship path panel 550 provides another, different visual presentation of the context of data. As illustrated in GUI 500, the relationships defined between entities in relational data model 200 are represented in navigation route panel 515 as 260, 275, 265, 280, etc. and the relationships defined between entities in relational data model 200 are represented in relationship path panel 550 as relationship 265, relationship 260, relationship 275, etc. for the purposes of simplicity and explanation. One of ordinary skill in the art will realize that GUI 500 may represent such relationships differently in different embodiments. For example, relationship 260/260 may be represented as “Person to Personal Info Relationship,” relationship 285/285 may be represented as “Job Info to Manager Employment Info Relationship,” relationship 275/275 may be represented as “Person to Dependents Relationship,” etc.

Returning to FIG. 4, process 400 then receives, at 450, a selection of a determined navigation route for a data integration operation. Referring to FIG. 3 as an example, UI manager 310 may perform operation 450 by receiving a selection of a determined navigation route from client 305 through a GUI that UI manager 310 provides to client 305. In this example data integration operation, after selecting navigation route 525, a user of client 305 selects UI item 560. In response, UI manager 310 receives the selection of navigation route 525 as a navigation route for a data integration operation from client 305.

Finally, process 400 performs, at 460, the data integration operation based on the selected navigation route. In some embodiments, process 400 may receive a selection of one or more systems on which the data integration operation is performed (e.g., via a GUI provided by UI manager 310 to client 305). In other embodiments, the one or more systems on which the data integration operation is performed is preconfigured.

Referring to FIG. 3 as an example, UI manager 310 may send the selected navigation route and specified systems 115 to data manager 320 and request data manager 320 to perform operation 460. When data manager 320 receives the request, data manager 320 retrieves the requested data based on the navigation route and sends the requested data to the specified systems 115 for integration into the specified systems 115. In this example data integration operation, data manager 320 retrieves the last name of a manager of each person in data source 105 and sends such data to the specified systems 115 for integration into the specified systems 115.

An exemplary computer system 600 is illustrated in FIG. 6. Computer system 610 includes a bus 605 or other communication mechanism for communicating information, and a processor 601 coupled with bus 605 for processing information. Computer system 610 also includes memory 602 coupled to bus 605 for storing information and instructions to be executed by processor 601, including information and instructions for performing the techniques described above, for example. This memory may also be used for storing variables or other intermediate information during execution of instructions to be executed by processor 601. Possible implementations of this memory may be, but are not limited to, random access memory (RAM), read only memory (ROM), or both. A storage device 603 is also provided for storing information and instructions. Common forms of storage devices include, for example, a hard drive, a magnetic disk, an optical disk, a CD-ROM, a DVD, a flash memory, a USB memory card, or any other medium from which a computer can read.
